No, the Vertigo titles won't get heat because frankly, they aren't that good. Saucer Country/County or whatever is going to be limited by it's political tone. The New Deadwardians looks cool, but it will be thwarted by the art. With that being said, I really liked Dominique Laveau: Voodoo Child, but I don't ever see it being "hot".
I hate to say it, but If the creators really believed in these titles, they'd be Image books. In the future, Vertigo may end up being the farm system for Image.
On the other hand, Scalped #1 is starting to pick up a tiny bit of steam. That's long overdue in my book.
